| 摘 要： | 采用界面聚合技术获得了新型信息记录材料光热敏微胶囊,利用红外光谱技术研究了外部环境因素对包裹聚合体系自由基聚合的影响.实验结果表明:聚合体系经包裹后曝光瞬间聚合速度与程度迅速增大,氧对微胶囊内部自由基聚合抑制作用不明显,但单体不饱和双键最终转化率降低;囊芯单体的聚合速度与程度随曝光强度的增加而增大,不饱和C=C双键转化率与曝光能量的平方根Ⅰ]1／2具有很好的线性关系;温度对微胶囊内部自由基聚合影响明显.

| Abstract: | The light-thermal sensitive microcapsule is synthesized with interfacial polymerization method,which is a new type of optical information recording function material.The influences of environmental factors on the free radical polymerization in microcapsule are studied with infrared spectroscopy technology.The results show that the speed and degree of polymerization increase rapidly at the moment of exposure,and the inhibitory effect of oxygen on free radical polymerization is not obvious in microcapsule,but the final conversion ratio of unsaturated C-C bond decreases.The speed and degree of polymerization of monomer in microcapsule increase rapidly with the light intensity,and the conversion ratio of unsaturated C-C double bond has a good linear relation with the I]1/2.The temperature has obvious effect on the polymerizing process in microcapsule. |
